Funding Amount

Summary

This project will enhance the drought resilience of farmers who manage 3 million hectares of sandy soils in the low-medium rainfall landscape of southeast Australia.

This will be achieved through the adoption of practices that enhance the productive capacity of sandy soils by overcoming constraints including water repellence & compacted layers that prevent root growth & access to moisture & nutrients.

Practices proven to work in small-scale trials will be scaled-out at 16 demonstration sites to build farmers’ confidence across an extensive landscape of the Eyre Peninsula, Upper Yorke Peninsula, Mallee & Southeast regions.

Case studies will be used to document outcomes from sites, with this information extended directly to 400 farmers through 17 events implemented by a consortium of grower groups. The project will also disseminate case studies using a digital extension hub & established social media networks to ensure maximum impact with farmers managing sandy soils across Australia.

Project partners:

The consortium is made up of 4 grower groups and a university:

  • Ag Innovation & Research Eyre Peninsula (AIR EP)
  • Mallee Sustainable Farming (MSF)
  • MacKillop Farm Management Group (MFMG)
  • Northern Sustainable Soils (NSS)
  • University of South Australia

Delivery partners include:

  • PIRSA
  • GRDC
  • CSIRO
  • Frontier Farming Systems
  • Trengove Consulting
  • Soil Function Consulting

The project has been funded through the Future Drought Fund’s Drought Resilient Soils and Landscapes grants program and the Grains Research & Development Corporation, and is supported by the SA Drought Resilience and Adoption Hub.
